Heya folks,
Is there a way to assign vertex color noise (like fractal or perlin) on an object but on the element level? I want each hexagon to have it’s own color but combined they create the noise/gradient effect. This would then be animated in Unreal through the material shader. I looked into baking vertex animation but there’s just too many vertices on this mesh for Unreal to handle. Thanks.
So every hexagon should have a single solid color, right?
Yep exactly. I just found a way to do this with Houdini but I’d be curious if that’s possible in Blender. Here’s what it looks like in Houdini
Yes, here is a setup. I used Geometry Nodes for it. I am not sure if it is possible with a shader alone.

In Geo Nodes you store the noise texture as a face attribute. You then feed this attribute into a color ramp in the shader.
Oh wow, thanks for replying so quick with the setup. This is exactly what I was looking for! Gonna see if I can animate this in Unreal now
